> They seem to go to great lengths to make sure that your results page has something on it by any means necessary

You just described how YouTube's search has been working lately. When you type in a somewhat obscure keyword - or any keyword, really - the search results include not only the videos that match, but videos related to your search. And searches related to your keywords. Sometimes it even shows you a part of the "for you" section that belongs to the home page! The search results are so cluttered now.
